[Inaba COZY] Iinari Chapter 4 A Lesson in Discipline from Father to Son

When young Jun's grades slip, his father resorts to a shameful punishment—locking him in a chastity device—under the thin guise that the boy must be "disciplined" against touching himself. The naive son obediently complies, unaware that daddy intends to push his "lesson" much further in the bathroom, where the tight ring is finally removed and the boy's trembling arousal is put on full, unwilling display. Torn between stern authority and undeniable desire, father and son blur every boundary of blood, control, and consequence in this intensely intimate power struggle.
